ioc_init

#include <file_config.h>

int ioc_init  (
    FAT_VI* vi);            /* Pointer to media control block */

The function ioc_init initializes the FAT Media device.

The parameter vi is a pointer specifying the media control block.

The function is included in the library RL-FlashFS. The prototype is defined in the file File_Config.h.

This function calls the Init function of the underlying SPI, MCI, or NAND media driver.

note

Support for ioc routines is only available on Memory Card and NAND Flash drives!

• 0 - on success.
• non-zero value - on failure.
